摘要

研究目的:寻找在隧道施工地质超前预报实践中存在的间题和预报重点,理清现阶段施工地质超前预报 工作思路。
研究方法:通过对隧道施工地质问题的回顾与地质预报工作现状调查,对主要的几种隧道施工超前地质 预报手段及特点进行归纳,从手段和方法上对存在问题进行分析。
研究结果:得出了隧道施工超前地质预报的工作重点是灾害性地质的预报,应结合地质理论对工程安全 稳定性进行评价后作出,而不仅仅停留在对不良地质体的探测上;提出了地质超前预报纵、横向探测范围的建 议值。
研究结论:地质预报工作是信息化施工的延伸,预报应考虑施工过程在地质体上的作用,探测技术可尝试 对开挖面前方地质体工程特性进行监测与控制等观点;提倡制定地质预报规程,统一作业水平,建立地质预报 评价体系,进行多手段、多方法的协同预报思路。

Abstract

Research purposes:The purposes are to seek the key points of geology forecast in advance for tunnel construction, find problems and make clear the thoughts on geology forecast in advance for current construction of tunnel.
Research methods :Through review of the geological problems in tunnel construction and investigation of the present situation of geology forecast, the summary is made for means and their characteristics of geology forecast in advance for tunnel construction arid the analyses are made for the problems from the areas of means and ways.
Research results:As a result , the key point of geology forecast in advance for tunnel construction is to forecast disaster geology which should be made after making an evaluation of construction safety and stability with geological theory and should cover a wide range,except survey of unfavourable geology. The suggested values of the vertical and lateral survey ranges are put forward for geology forecast in advance.
Research conclusions: The following views should be had; the work of geology forecast is an extension of informationalized construction, the geologic process should be taken into account in the forecast and the prospecting technology should be tried to monitor and control the characteristics of geology in front of excavation face. The following coordinated forecast thoughts should be encouraged: the geology forecast rule should be worked out, the operation standard should be uniformed, the evaluation system for geology forecast should be established and many means and ways should adopted together.
